APPARATUS ron `scoUmNciv on .CLEANING rma INTERIoRs or Pires on "iuisiszia T o all uzom it 'may concern:

Be itjkno'ivn that I, HEiNnicii Wim-inni B'rz, a subject of the German Emperor, and resident of LudWigshafemonfthefllhine, Ger- 5 many, have invented certain new and useful Improvements in Apparatus for Securing or `Cleaning.; the Interiors of .Pipes or Tubes, of

7 which the following is a specification.

When pipes oi' tubes, are `to be galvanized i on their interior, it is necessaiyto first clean 1 theiii thoroughly. This is done .by vfirst treating the interior of the pipes, or tubes,

' ivith a pickle and then'scouring, oif cleaning. This'scouiing, or cleaning especially when it i y i has to be done on a large scale presents'great diftieulties as it is. a very laborious and lengthy operation and its proper execuf tion depends entirely on the skill and care of the operatois, and it cannot be properly Watched.

It has been attempted to eilect the-scouring, or cleaning, by brushes arranged in an endless seiies, or by spirally arranged brushes, but this does not suffice to effect the proper scouring, or cleaning, as the hammer slag and iron scale adhere so irmly to the inner Wall thatv it is difficult to remove them by brushes alone.

This invention has foiits object to effect the scouring, or cleaning, operation in such a ina-nner that it does not depend upon the careful Work and skill of the operators, and is less laborious and more ex editions in its .execution than the methods ieietofore employed.

Apparatus according' to this invention con sistse'ssentially of an endless chain, or band, Iof brushes, at a short dist-ance apartand a trough containing a scouring medium such 40- as sand, or sand and water, to which troughthe pipe, `o1" tube, to be, scoured, or cleaned,

is connected, so that the brushes pass' throughthe trough and carry scouiing,or cleaning, inediumrinto the pipe, or tube, so

' 45 that the scouring, or cleaning, medium is distributed uniformly therein and as the passage of the brushes and scouring, or cleaning,

medium, is constantly repeated, a continuous and systematic scouring, or cleaning, of the v interior of the pipe, or tube, is effected,

It desired, in order to obtain a still more elii'cieiitf scouring of the interior of the pipe, ""'or tube, 1t may, during the scouring opera.-

Speccation of Letten; Patent. Application filed January 7, 1908. SerialNo. 409,647.

Patented sept. 22, 190s.

' teriiiittent, rotation on itslo-ngitudinal axis. 55'

This rotation has proved very well and in i this case one can be (uite sure that the intea portion corresponding to the length of the pipe, or tube, and replacing this portion by a wire over which the pipe, or tube, 1s passed and when the cha-in, or band, is set in motion and the.' end of the chain, or band, at-W tached to the end of the Wire issues from the pipe, or tube, the cliain,'orj band, is stopped andI theivi-re is ren'ioved and the removed part oi' the lchain, or band, is restored to its original position.l

The motion of the chain, or band, is .eiiected by chain Wheels, or disks. For this purpose the bodies of the brushes can be provided with cofaxialfextensions and articue lated ends, which, like the link sof'ordinary endless chains,`enga re the teeth ofthe chain 8o wheels, or disks, While the brushes enter correspondingly shaped recessesv between the teeth of the chain wheels or disks. The trough' containing the scouring, or cleaning,

vmedium is closelv connected tothe front end ofthe pipe, or tube, to be cleaned. The scouring, or cleaning, medium can be supplied to Vthetrough by a hoppen, vi'hile Water can be' supplied through a pipe inv proximity' to the outlet from the hopper.

The accompanying drawing is a side view of the apparatus partly broken away.

a are t ie chain Wheels over which pass the ,chains b which are provided at' suitable dis tantes with brushes c ivhich, when thechain .is in movement successively come in gear with recesses d ofthe chain wheels. The chain moves in the. direction of the arrow e through the tube. f to be scoured or cleaned when .the brushes carry with them sand from the receptacle z. fed b v the hopper g. By the t'ube'i water is supplied to the sand which falls into the receptacle h.

The herein described apparatus for scouring orclea'iiing the interior of pipes or tubes which consists of an endless `chain or band tion, have imparted to it continuous, or inprovided at short distances'with brushes in combination with .a trough containing a scouring` medium to' whichtrough the pipe or tube t0 b e scoured or cleaned is connected so that Vthe brushes pass through the trouglrand carry scouring medium into the pipe or tube substantially as and for the urpose set forth;

In testimony whereo' I have signed my `ns1-lne to this specification in the presence of two subscribing Witnesses.
